When every someone says it's too late in life to do something, I like to remind them that Toussaint L'Overture (a former slave) [1] was almost 50 when he led one of the most successful slave rebellions, defeating all of the colonial powers at the time (France, Spain and UK) and laying the ground work for the first independent black state in Carribean.

Just a nice example that it ain't too late.
