You got room to store all your tools in the flat? Go steady with workload, no late evenings 7+ as it really will take its toll after a couple months, can feel overwhelming, but slow and steady wins the race in these situations.
Its only a one bedroom flat, don't have much stuff, mostly tools, they are all left at parents house Not going to start anything here, mostly OK, just needs some painting.
If you start incorporating a friendly nearby public house into day to day life for a spare hour here and there, you'd be amazed how painting the flat goes right down in the list of priorities......
