You must be merciless with yourself. Select the most important project, get a piece of paper and write down everything that needs to be done in bullet points. Write down the minimum and maximum time you believe each should take. Figure out the maximum amount of time you can work each day (10 hours is long term, every day sustainable rate for me, doing more imho leads to diminishing returns). Do the same time evaluation for every other important project and then reevaluate which is truly the most critical. Work on that critical project only until it is done, mercilessly without deviation.
