I used to say this:
Don’t be shy!
Do be curious!
Do stare !
Don’t be too analytical, use your intuition … sometimes it makes a big difference
Do help people!
Don’t try, do!
Do save your files once in 5 minutes, in a electricity world, ideas are related to electrons!
But now I am saying this:
Always be true to yourself!
Life is THE most valuable gift you received. Make it count!
Start doing! You have everything you need already for what you want to do.
Listen to your intuitions and act on them!
Help others when asked!
