could take some small classes at like a community college or technical school.
We have a VoTech around here that offers Night Classes in pretty much everything they teach durring the day for students.
So for about $400 I could go do 2 times a week for like 6-8 weeks and learn welding (level 1 or 2), carpentry, HVAC, computer maint., cosmetology, nursing, food prep, electrical, etc. Trade skills basically. But they can come in super handy for the future.
