Just do it

Nobody makes a greater mistake than he who does nothing because he could only do a little.

Edmund Burke

How many times have you done nothing because you thought you cannot do enough? How many times you thought you cannot make a change and decided to only be a spectator? Imagine what could have happened if only you've taken action - even so it might have seemed a really small step at the time, it could've led to something amazing. 

Next time, just do it.
