why should you keep going?... i dont know! i can only know myself... but here is what i do know: no one ever made it very far from giving up. maybe you forget to fuel your tank with gas; no worries, here is a little bit of fuel you can use to keep going... you should keep going because... because there is no glory in living scared. you should keep going because there is all the glory in TRYING HARD and CARING A LOT; even if you fail you can say you really did try and know you tried HARD. knowing you tried and then realizing you can keep trying, realizing that all the results come almost randomly right after a long long time of self doubt, and then one day everything starts working.. after a long time of nothing it all comes at once.
imagine you were just a wee lad and you dreamt of making it big... now remember we all were once that wee lad, even the guy who has now made it big in all the ways his wee self used to dream of, pinching himself to check its not just one long dream.. but how could it be, after all: for years he thought to himself "will this ever work, am i trying hard enough, do i care enough, why ME?"
WHY NOT YOU. someone else who with half the brains (who is twice as stupid, in other words) has done it... so WHY NOT YOU. keep going. ENJOY THE JOURNEY. ENJOY THE LULS. stay curious and keep trying hard while caring a lot. you will eventually make it to where you are aiming and then you can realize there is no place to stop, there is only room to keep going with the reaper of the past at your heels. good luck now, buddy.
