Are you new with this hobby and don't know where to start?
Well, I got good news and bad news for you.
Good news are that there are a lot of themes.
Bad news, same than previous statement.
So, I decided to write this as a little help so you can find an anime/manga that you consider suitable for your likes. Although I must say first that some of this haven't been watched/read by your server, so maybe you may ask for a second opinion on them. And yes, like a school work I will give the credits to the sources at the end, so you can take away the mouse from the     -reputation button.

The basics:
Manga has categories, called demographic, to determine more-less which is the target audience by age.
Kodomo (less than 13 yo)
Shonen/Shounen (12 - 18 yo, boys)
Shojo/Shoujo (12 - 18 yo, girls)
Seinen (19 - 40+, men)
Jisei (19 - 40+, women)
Needles to say, boys also consume shojo/jisei and girls shounen/seinen, even when they are not the target audience.

And for both manga and anime we got the themes, also can be referred as genre. These are the tags that, well, tag the work with a certain or group of themes. Can't give a complete list because I don't know if even there's one out there, but for starters we can say it's something like this:

• Action
  
• Adventure
  
• Comedy
  
• Romance
  
• Harem
  
• Slice of Life
  
• Psychological
  
• Mecha
  
• Ecchi
  
• Horror
  
• Historical
  
• Yaoi
  
• Yuri
  

The majority is pretty much self-explanatory, but I will explain copy the description from other site for a few of the list.
Slice of Life: Like a journal or diary, mostly like a story of young memories.
Mecha: Giant robots.
Harem: One boy with many girls after him.
Ecchi: Sexual jokes, fan-service, almost if not always accompanied with Harem.
Yaoi: Love between boys.
Yuri: Love between girls.

One of those tags may be the main over the others, depends of the story.

So, where do I start?
There's not a tier list nor an official tour to follow, mostly depends on you and your likes.
But you entered to this post to find something to start so, here are some options.
Mecha:

• Neon Genesis Evangelion (Counts with movies, might as well save for later)
  
• Real Suit Gundam (Old, but it's something classic)
  
• Voltron
  
• Gridman (Maybe a bit to general, it's a whole series from more than a decade or so)
  
• Tengen Toppa Gurren Langan (More according to this days)
  

Slice of Life:

• Nichijou
  
• Fruits Basket
  
• Hibike! Euphonium
  
• K-On!
  
• Heidi (Old, again, a classic)
  

Harem/Ecchi:

• High School DxD
  
• Shinmai Maou no Testament
  
• Omamori Himari
  
• Rosario + Vampire
  
• Mato Seihei no Slave (Anime not out yet)
  

Military:

• Girls und Panzer
  
• GATE jieitai
  
• Nihonkoku Shoukan (Has no adaptation to anime)
  
• Zero no Tsukaima
  

Comedy:

• Bleach
  
• Konosuba! (Mainly story described on the Light Novels)
  
• One-Punch Man
  
• The Way of the Househusband
  

And here are some honorific mentions that I was lazy to give them a category:

• Death Note.
  
• Full Metal Alchemist (Don't ask which is better between the original or Brotherhood).
  
• Full Metal Panic! (Totally unrelated with the previous, seriously).
  
• Kill la Kill
  
• Re:Zero
  
• Captain Tsubasa (Must warn you, those football fields are the largest in all sports' history).
  
• Shingeki no Kyojin
  

Here ends this humble effort to help you start in this world. Must say I'm a bit obsolete since I stopped watching new series since 2 - 3 years ago, so maybe there are some animes that could cut it to start.
Also, if you are more experienced or a non-starter, please, avoid starting a war in the replies, this is intended for the new ones, so, if your favorite anime isn't on the list, you can recommend it as well for the newbies. This list is not intended to be a tier-list, good or bad, so I ask you respect.

Fun fact: Full Metal Alchemist Brotherhood is the original because it came from a manga. Both series are based on an original manga series. Fullmetal Alchemist began when the manga was being made. The manga was late in releasing and the anime caught up with it, so the creator couldn't stop the anime and therefore created his own story. So the anime is not based on the manga, it has a completely different story. FMA Brotherhood was adapted when the manga was finished, so it could follow the manga's storyline. So when you say "Don't ask which is better, the original or Brotherhood", Brotherhood is the original, the other is just the first version. Therefore, Fullmetal Alchemist is non-canon and Fullmetal Alchemist Brotherhood is canon. FMA Brotherhood>>>>>FMA this is my opinion but FMA is cool to watch We say josei and not jisei And for captain tsubasa I totally agree with you lol they do 2 episodes before arriving on the other side of the field plus when tsubasa or Hyūga want to shoot they take all their time and pose as if there were no defender not to mention Ken who does karate at the instead of keeping the goals. Otherwise it's a very good summary. you did a good job. keep it up

Thank you for the correction! I have to be honest, didn't watched any of the releases of FMA, but not including it would be a bit weird. Also have to say the sentence I wrote between () was to avoid a fight. I could be wrong, but slightly remember been a hard topic between FMA which release was better. Anyways, again thanks for pointing that, I will update the post.
