Looking for my first job in the field.. Former Military

I’m 22 been out of the military for about a year now and I realized I want something similar to it.
Being away from home, manual labor, long days, always occupied, disciplined. I live in Houston.
I’ve tried so hard to get into this industry but come up empty handed… I don’t know if I’m looking in the right places.
If anyone can help me that would be greatly appreciated. Thank you!
