Do you think I should switch to part time instead of full time?
Why do you want to switch to part time?
My commute is so long, I would rather work less days per week to avoid commuting everyday.
If you think you'll be happier and make enough money to pay your bills, then you should switch to part time. It's important to be satisfied with your job.
I think I'll try working part time and see how I like it.
If the commute is making you unhappy then it's a good idea to go to part time. You'll be more productive if you're happier because you're not commuting as many days during the week.
