Suggest me a Few MOTIVATING Manga that makes me wanna Succeed in life no matter what.

Densha Otoko
at least romance-wise

________________
in need of romance?
uncommon, sad, sweet

Solanin and Fever
well umm...in both of them the main characters failed a lot before because they were submitting to social standards instead of doing what they really want to do...they both might be a little depressing(and they both contain deaths of side characters) but they both have the believe-in-yourself-and-your-abilities conclusion

Onani Master Kurosawa

http://www.mangaupdates.com/series.html?id=33759

Basically about a social recluse who's a bit sick in the head. Makes mistakes and his life hits a real rough low point. But he obtained extreme desire to change himself for the better, and worked really hard for his redemption and earn the forgiveness of the people he wronged.

Vitamin (SUENOBU Keiko) its only one volume , but its motivating enough ... imo

Strongest Man Kurosawa. The most motivating manga I have ever read.

Whenever I read Yanki-kun to Megane-chan it motivates me to study more.

Welcome to the NHK - the anime was quite motivating (not sure about the manga and novel)

P.S. It actually motivated me pass two exams (which I initially failed) I was about to drop out from Uni because of those.

I second "Welcome to NHK" ^^

My personal ones were
Skip Beat!
Historie.

Manga that truly motivates me is well-written, well drawn and an absolute page turner manga that I cannot stop skimming through again and again. Like Monster. Or Flowers of Evil. It assures me that talent and a special something can take you pretty far, in making works of art that will entertain many.

In all honesty, manga can never motivate me enough. It's there for fun or comfort but motivation is a bit far.

Ookiku Furikabutte. Well at least for me, motivated me to do some changes in my life (of course connected with sports) but yeah i've done something i though i'll never do again but this manga made me change my mind.

for me there's ashita no ousama, cat street and honey and clover

also, G Senjou Heaven's Door, but that was a bit forceful

and I have no idea why, but sakuran.

if there is an option between "to do" and "not to do", I will always choose the latter.

"what kind of crazy, twisted conclusion is that...?" - banana bread no puding

I second Honey and Clover (heartbreaking though) and Cat Street!
Also, other good ones are Kuragehime , Dengeki Daisy and Mars

As they played the game...I waited for someone to call "onigiri." But no one called. I was very little then. I had almost forgotten about that. [...] But they knew...there would never be room for an onigiri...in a fruits basket.

This manga inspired me so much xD
and also, Yumeiro Patissiere xD well, the anime inspired and motivated me a whole lot more

Hajime no Ippo is #1 most motivating manga for me.

The Legendary Moonlight Sculptor (Novel) at the beginning.

Bakuman at the beginning is good for specifically motivating me to draw.

Sports manga like Eyeshield 21 and No Side tend to be good at motivating.

i agree completely with bakuman ( the beggining was very good and motivating allthough it eventually started getting repetitive closer to the end i found but still a great manga) hajime no ippo was pretty motivational and good as well, i know that there are a few others for me but i cant remember their names for the life of me only the story, ow well
