Hey @Christian Francois
I promise, you do not need a mentor! If you want a mentor, there are plenty of paid options out there. However, you will not find a "free" one by posting on sites like this. You best bet would be to network you but off, both online and in person. Eventually you will find someone who is experienced and looking for help in their business. If you can show them that you have value to add to their business, they will likely take you under their wing to a certain extent. Many of us have had "mentors" like this in the beginning that have helped us get to where we are today. Many of us still have mentors and always will. However, I doubt any of us found mentors by asking for them, unless we were also prepared to pay for it.
There are so many resources online, in books, at networking events, etc. that, honestly, you really don't need a "mentor," at least not in a traditional sense. Let the wealth of information out there be your mentor. You'll likely end up more well-rounded and unbiased that way too. That's where I would start; that's where most of us started - Learning. Trust me, if you've digested enough information, a path will begin to emerge. If you have no clue how to start, you likely just haven't educated yourself enough.
And remember, you always have crowdsourced mentorship like BiggerPockets to ask questions. You won't always get an answer or at least not the one you were expecting, but it's a low-cost way to find answers to specific questions.
Hope this helps a bit. Please, feel free to reach out anytime if you have other questions or just want to chat!
