I've been working for the last 5.5 years in sales and projects. I kinda don't feel like doing anything anymore. Why do you think it could be? 
Things on the personal front are okay. I just find it hard to be consistently driven. 
This is my 4th company now. Got laid off from 2, and left 1 due to the pandemic. 30 y.o. now, single with an MBA with a niche specialisation from a decent college, which isn't being used anywhere. 
Had to take a pay cut while joining this one. Big chunk. Talk about ESI level salary. 
Feel a lack of growth in professional tools, and completely demotivated to even learn despite buying a million courses online, can't join FT cos obviously I can't stop working rn. (Sigh)
