“Difficulties are mean to rouse, not discourage. The human spirit is to grow strong by conflict.” – William Ellery Channing
Staying away from difficulty is often a foolish choice. While it may provide a temporary reprieve the challenge will eventually rear its head again. No matter what difficulties must be dealt with. Might as well Do It Now.
“You are never too old to set another goal or to dream a new dream.” - C.S. Lewis
Don’t let situation and circumstances keep you from doing something new or different. This directly relates to what you do in the day to day. Change is always hard(see above) but that doesn’t mean that it shouldn’t be done. You should probably Do It Now.
“If only people knew how hard I word to gain my mastery, it wouldn’t seem so wonderful at all.” – Michelangelo Buonarroti
Mastery comes from grinding it out every day. Your skills only atrophy when you stop working. Always keep learning. Yes it can be hard to do(see the first quote), yes it might take longer than it once did(see the second), but it was going to be hard anyway so you should Do It Now.
