"Don't try to do it, just do it"

what's the difference of try and do?

try - v. - attempt
do - v. - perform, complete

if you just try, you just attempt and nothing will happen.
if you do, you perform it, COMPLETE it.

try: 50% you won't do it, 50% you will do it
do: 110% you will

try: if you try and try, your percentage of "will do" will drop and drop
do: if you do and do, your percentage of "won't do" will drop and drop

try: more of a negative word
do: more of a postive word

try: better than nothing
do: best than the rest
