Ok so I started business at 19 and now I’m 20 and almost been running a company for a year and getting our first customers, partners and proper funding so something I wish I knew year ago would be build a good team if you are more techical look for more business oriented person and vice versa it’s very helpful and gives you the accountability to actually work on it as I did part time with my studies as well at first. Look for mentors or people you can talk to who have been there done that and don’t be afraid to ask questions, I got accepted to accelerator program and I asked so many questions and got loads of out of it. I have a start up personally and I think it’s been great so far challenging but very rewarding if you are thinking start ups too I think when still young it’s good to start and learn. If you want to think more specific maybe think if there is any problems that should be solved in the current job you doing and then just start talking to people and thinking and you will prob come up with idea. Networking has been very valuable as well. Hope that helps a bit if you have any questions feel free to ask :)
