I would strongly urge you to get a part time job with a landscape company....one that does stone work, bed installs, plant installs etc. I did this all thru college and some of the things I learned 25 years ago I still use today. You will also find out just how hard this work is and whether you like it enough to bust your butt like most of us do day in day out. After all these years I still love this business....and that is what will make you successful.
