Everyone started out like that, so don’t get discouraged. The key is to excercise the estimation muscle. Keep logs about your estimations and how long it actually took. Then think through periodically what caused the big differences. This way in the long run you’ll be able to precisely estimate tasks you’ve sort of already done in the past, and can estimate a reasonable low/high time range to finish tasks which you’ve never done before.
