A few things.
First, if you save 50% of your take home pay, you can retire in 15 years.
Second, fund first a tax-deferred account. If you don't like your employer's 401k, open a traditional IRA somewhere. Lots of people like Vanguard for that.
Third, before you do that second thing, open a savings account and build up an emergency reserve fund. Get it up to at least 6 months worth of your BASIC expenses -- not counting vacations, gifts, eating out, etc. Even better would be one year's worth of expenses (which is what I have done).
Good luck.
