You soon come to associate that spot with the tranquility of deep concentration, and that association helps you to reach deep states more quickly. The main thing is to sit in a place that you feel is conducive to your own practice. That requires a bit of experimentation. Try several spots until you find one where you feel comfortable. You only need to find a place where you don't feel self-conscious, and where you can meditate without undue distraction.
Many people find it helpful and supportive to sit with a group of other meditators.
The discipline of regular practice is essential, and most people find it easier to sit regularly if they are bolstered by a commitment to a group sitting schedule. You've given your word, and you know you are expected. Thus the 'I'm too busy' syndrome is cleverly skirted. You may be able to locate a group of practicing meditators in your area. It doesn't matter if they practice a different form of meditation, so long as it's one of the silent forms.
