There are an infinite number of things you can do with your finite amount of time on this earth, so keep in mind you can never do everything! Comparing to other people isn’t productive, but measuring your own satisfaction can be. I’d try making a plan for your leisure time to begin with, and get outside a lot more, nature is so satisfying and calming. Remember that it’s amazing to be here and alive at all, no matter what you’re doing, so try to enjoy every moment with that thought in mind.
Edit spelling.
Try boiling a kettle, filling a bowl of water, pop it in the oven on 100 for 30 minutes. That will soften it up. Then you could also try a paste of bicarbonate and water painted on and leave for a while. It might take several goes.
When it’s done, buy a silicone liner for the bottom and wipe out the sides and roof with soapy water every time you use it. It saves sooo much time in the long run.
Good luck!
