Christmas Windfall

I received a big cheque for Christmas – unexpected and fabulous. My debt is gone. My taxes are paid. I will now have extra cash every month ($1500ish) to do whatever I want with – save for a house, plan regular travel, build my retirement savings etc. What I am realizing is that I have been in debt drama for so long I am not sure what the right/best/appropriate decision is and can’t help but think that lines up with weight loss/reaching weight goal – when the struggle is over, what is left? How do I decide what to do with my extra $?
Thank you and Merry Christmas!!
