I’m currently 35, I will be able to retire at 38. Married, one kid, one on the way.<p>* Don’t rent in a high cost of living location; purchase in such a location only under the assumption that your property might lose value<p>* Don’t waste money on depreciating assets (never buy a new car, no iPhone upgrade cycle)<p>* Do live below your means, keep your expenses in check, credit card debt must be avoided like the plague; no cable TV, cheap phone service, no Starbucks<p>* Do save at least 15-20% of your pretax income in retirement accounts, the more the better (contribute enough to your 401k to get company match, then max IRA, then contribute again to 401k up to annual limit, then taxable accounts, generally); I suggest a low expense ratio target date fund for retirement accounts, with anything above %0.20 being exorbitant<p>* Don’t value your ISOs at anything above $0; cash is king<p>* Don’t get attached to your job; you are a mercenary, attempting to extract as many dollars per hour as you can (either FTE or freelance); friendly coworkers and beer in the office fridge doesn’t cover retirement expenses<p>* Do be interviewing and job seeking passively to stay practiced and ready<p>* Do fund ways to invest in productive, income generating assets (rental properties are my thing, YMMV)<p>Good luck!
