A smart man once told me that when someone offers a life changing amount of money for something you've built, take it. It's a rare opportunity and you'll still have plenty time left to build something new once more.
Love this! You can always build another business with a fresh new mindset.
1 - Get a job, in something that makes you money. You need money to survive and you need experience in something. So get a job and understand you will be in this job for at least 6 months to get your savings up. Remember: You're 24 yo. Stop rushing. There is no 'get rich quick'. Even the guys who sell 'get rich quick' courses online (spoiler alert) THEY. DID. NOT. GET. RICH. QUICK. They probably worked 9-5 for a few years, studied digital marketing and learned how to get results using the internet. This takes time, you gotta study, you gotta test and for that to happen, you need money. So focus on that first. Work in sales or as an sdr or something, go to weworkremotely or glassdoor or indeed or linkedin and work from home.
2 - After you get a job and stick with it for a few months, studying every day, saving up some money in a fund, reading lots of books, going to the gym, eating healthy, etc, then post here again and we'll give you the next steps.
