I picked YOLO only because I really do think "You Only Live Once" so make the best of it. I do hate the term YOLO though, yuck. Lol. I am so dysfunctional its hysterical. Haha. But to answer your questions one by one. I will try my best.

If you've ever felt like life is pointless...

What do you now believe is the purpose of life?
To live for my family and to make myself a better person and to make a difference in my life and my community. To reach out to others and to help others and to write just write and write and write!

What do you live for?
I kinda answered that in the above question, again with the dysfunction!

What would you suggest for people who feel nothing is worth living for, even the good things?
Look around you, step outside your door. Call a friend. Connect. Even if it is online or in person.

How did you decide this?
People make me feel better. Even if they are over the computer screen, being part of a community such as this one brings me great joy even though I may take long breaks and not come for a while.

Phew!

I hope I did well, I know its not a test but again its my need to please!
