1.) You are outdoors. Which is not always a great thing here in FLA in June, July and August. You can pick up skills without going through school, like irrigation, plant selection and insect issues.
2.) I never hired anyone with facial tattoos. They had to have a clean record. It is very hard to find people with decent driving records in my area, too many DUI's. But, have a good driving record was important. Finally, being able to learn how to do the job correctly and be able to communicate with me was very important.
