- Articulate your goals, risk tolerance, and investment horizon
- Determine your asset allocation
- Commit to an investment strategy and stay disciplined
And if you have problems answering any of those, I suggest reading these free series:
And an extra resource: Investment Taxes in the Netherlands.
