Another thing to consider if you are adequately insured. Investing more money or more aggressively will do little to protect your family from a major catastrophe next month.
Do you have:
-life insurance - This should compensate for lost income, cover the mortgage for the spouse, and expected future college tuition
-Disability Insurance - Most employer disability insurance leaves you under-insured. Make sure you have an additional policy that will actually protect your family
-Adequate liability coverage - You need enough coverage on your home and vehicle to protect you from lawsuits. If you t-bone a person in a ferrari in your civic, do you have enough coverage to protect yourself? Also, get an umbrella policy to act as a backup to your auto and homeowners.
-Finally, while you are at it make sure your wills and beneficiary setup is complete and done correctly.
Once the above is checked off, then you can focus on your investing. If you don't plan on hiring a professional money manager, then read up. In general, consistent investing in a broad basket of products is best for your longterm financial health
