Hi Michelle,
You can always work with visualisation, picturing beautiful, supportive Chi coming to your door. You can make a small quote about positive Chi flow coming to your door and place it in one of your success directions. There is always enough good Chi for everyone.
As for applying the feng shui especially time feng shui:
if you own an apartment, than you take into consideration your own front door. You do the feng shui according to the direction of your own door.
If you rent, you do the time feng shui in your apartment according to the direction of the main-front door. It is always good before you rent or buy to check the degree of the main door and the flaying stars combinations in the area of the apartment. The flaying stars of the whole building will affect you even if you own your place and do feng shui based on your front door.
Good luck,
Alexandra
