This should be self explanatory, but do whatever it takes to get that project done on or before the project due date you set. This should be your number one priority. Your ability to get future projects, the possibility that your employer will rehire you and most importantly, your income will depend on you getting projects done on time.
There will most likely be times where you misjudge the amount of time to complete a project. In these cases you may have to work “overtime” working more hours than normal or giving up your weekend to get it done. Just do it if necessary. This is part of the learning curve for the new freelancer and soon enough you will be able to better calculate a time estimate of a project.
