Depends on your definition of "try". "Trying" for a year or two doesn't cut it. Self made people put in a lifetime of effort. It's taken me over 30 years to get where I am. The real problem is, as I have said before, discipline and staying power, willing to hold to a vision through thick and thin, over the long haul. Most that bother to try come up with an excuse to give up. They make a bad choice or a series of bad choices.
I can take every person on this forum that is unhappy with their state in life, go over their life in detail from age 15 and on and pinpoint the three, four, five or so bad choices they made to get where they are. And it's usually the same things over and over again. Things like
1) Should have stayed in school
2) Should have pushed myself and taken college prep classes instead of the regular stuff
3) Should have majored in something I could have actually made money in, instead of something I could only make a living with by being a teacher....
4) Should have opted for the chevy instead of the bmw
5) Should have signed up for the $50/month payroll deduction for retirement back when I was 25
6) SHould have joined the military and let them pay for college...
7) Should have gotten so mad at my boss I just quit....with nothing else lined up.
8) Should not have shoplifted that blow drier....
9) My kids never needed Nike's when noname sneakers would have done fine....
10) Should have bought my clothes at Penny's instead of Van Maur and Lord and Taylor...
I could go on and on....
