If you feel that you barely have enough time to see your wife and kid, and that it's hurting your family, see if your entire family would be willing to do volunteer work with you on weekends. It would be a good experience for your kid too. Volunteer at a rescue mission or ask a local church if they have elderly shut-ins or disabled people who need housework done.
Don't waste a lot of time thinking about yourself and how you're wasting your life. Growing a beard won't make you a freer person. You'll become more discontent that you're insignificant and feel the need to make a grand gesture. This is how people end up leaving their family, their children, and turning up barefoot and naked in Tibet. Instead, start actively doing small things that make a difference to an individual. Your wife and child are good individuals to start with. Your kid will always remember if you take him camping or skiing and want to spend time with him. And a lot of other people have given you volunteer work suggestions.
