If you aim big, you’re gonna get it someday, just how no one always wins, no one remains a loser for life either. If you always aim small, you might get many wins, but it’ll still be small; if you always aim big, you WILL achieve something, at least once, and it’ll be a big win and that’s all that matters. Take small steps, take your time, its ok. But while aiming, try to shoot for the big shot. 

Here’s the thing, when you keep aiming big, the competition will be harder. But you’ll learn more and get used to the tough ones, so even if you don’t win, you’ll shine when your surroundings are easy, cuz you could survive for a while when every thing was on the difficult level.
