Hi Will,
I was (am) in your same shoes. I graduated with my degree at 28 and am now 32. I too have been on the fence about the industry at times since finding jobs is very difficult without the usual 3-5 years experience. I started doing my own projects on weekends for friends and through craigslist to generate my own experience and build my resume/portfolio, all the while working in an unrelated job. I’ve found that this field is very competitive and at times saturated so my approach has been to take on small residential front and back yards to get some experience. It eventually paid off and continues to do so, but it did take 3-4 years to see any results. Good luck, hope this helped.
