Everything comes to those who wait... except a cat.
If you wait, all that happens is that you get older.
If everything's under control, you're going too slow.
If everything seems under control, you're just not going fast enough.
Circumstances may cause interruptions and delays, but never lose sight of your goal.
I recognize my limits but when I look around I realise I am not living exactly in a world of giants.
Desire is the key to motivation, but it's determination and commitment to an unrelenting pursuit of your goal - a commitment to excellence - that will enable you to attain the success you seek.
Do it no matter what. If you believe in it, it is something very honorable. If somebody around you or your family does not understand it, then that's their problem. But if you do have a passion, an honest passion, just do it.
