My Mother used to tell me: If at first, you don't suceed, try, try and try again."

She also used to say "everyone cannot be good at everything. Pick something you like and pursue that. If it works for you, fantastic. If not, find a different thing and try that."

I picked and sucessfully pursued landscape design and maintenance, in the face of opposition from my father who felt I would never make it through school or university because "you are not smart enough".
