Well nakama, this will be my first anime card: yay! This topic is perfect, because after an anime or manga says something pretty deep, I find myself taking some time to their words over. So, take a look at what got me up and reflecting..
"Power comes in response to a need not a desire. You have to create that need." -Goku
You won't put the work in if all you do is want it.
"Speak of your future. And that shall become your will to live." - Igneel
Continuing along the same lines as Goku, when you have something to look forward to; if you need it to happen, then wouldn't do everything in your power to make it happen?
"When life changes to be harder, change yourself to be strong." -Erza
"There are no limits. There are only plateaus, and you must not stay there, you must go beyond them." -Goku
Life will always be filled with bumps, obstacles, and mountains. Be afraid all you want, just remember that there will always be something to be afraid of. If you keep moving forward towards your goal/dream/future, then those fears will be nothing more than a memory and proof of a life worth living.
