Fund management comes with great responsibility. Before managing funds for others, it is wise to have consistent and long track record (several months to be the least) to showcase to investors that you can be trusted to manage their funds with professionalism.
Get to know your potential clients on their goals and objectives and then as a fund manager, you decide if you can deliver it.
If you have all it takes to be a fund manager, go for it. And investors will come and seek you before you knew it.
