Stop Being Afraid

I read an article that a friend shared with me on 19 Things To Stop Doing In Your 20's.
Considering I am 25++ years old this year, it's a tad to late to starts but so?
I have about 4 years ++ till I'm turning 30, quite plenty of time still..
Of all the list, there are things that I really caught my attention:

#17. Stop agreeing to do things that you know you’ll never actually do. Well, it's okay to say NO. as I grow older,I realize saying NO brings a lot of different to myself. Literally.

#18. Stop ‘buying’ things you know you’ll throw away. Situation 1: bought a skirt that cost me RM250, wore it twice and yadaa yadaa.  Situation 2: Bought a slice of cake just because of sudden crave and had to run errand and have no time to indulge on it. End up, it doesn't taste as good as before and throw it away. Situation 3: things are all on sale so you buy 6 different colors of the same err tumbler/iPad cover? Can you see how's Satan tries so hard to fulfill your nafs?

#19. Stop being afraid. seriously, please stop. voice out your opinion, tell the truth even it hurts other people, do bungee jumping, go caving at night, go water rafting, try new things, register as an organ donor, take challenges. 

Well,LIFE is short.
