DIY vs Pro

When you look at a finished product of a DIYer or a Pro there is only one difference. The DIYer couldn't make it right because of the lack of practice. So, s/he made the final look as it is unintentionally. The DIYer does it for oneself, thus s/he is keen to do it right. If s/he really want it to look neat time and cost does not count. The Pro however made the final look as it is with purpose, because of the lack of time. S/he has to run for the next place or start the next piece to feed his or her family. Pro can do it faster and because of experiences and practice s/he can do it better. But, if s/he can't make it first s/he does not really give a damn. Unless the problem is capital. The Pro always try to find the simplest and fastest way to finish something. The DIYer does not really give a damn how hard to get to the end. S/he wants the final look neat and the apperance should look like a pro did it. So, the only difference is how hard you want to approach Perfect.
