Don't overload on company stock

Don't invest too much of your 401(k) plan contributions in your company's stock. Remember, even if the company is doing well now, things can change. And if the worst happens and you lose your job, you don't want to lose your retirement savings too. If your employer used company stock for the matching contribution, you may have no choice. But at least you can select other investments for your own contributions.

Can a Self-Emplyed person, who is still working full-time skip thier Pension/IRA RMD (Required Minimum Distribution)?

No. Generally, you must begin taking "required minimum distributions" (RMDs) from your qualified retirement plans and IRAs after you turn age 70 1/2. Then you must continue taking RMDs for each succeeding tax year.
However, you can delay RMDs from qualified plans if you're still working full time and you don't own 5% or more of the company.  There is no such exception for IRAs. Because your Simplified Employee Pension (SEP) is treated as an IRA rather than a qualified plan, you must start taking RMDs after you turn 701/2 whether you are still working or not.

So, remeber: In any event, full-time workers can't postpone RMDs from an IRA.
