There&#x27;s still a massive risk. What if you put three years of your life into a startup that becomes defunct after all that time?<p>Then you&#x27;ve lost three years of your life and have to go somewhere else.<p>Sure, you gain knowledge and experience through that time, but joining another company would still take time to work your way through the ranks there. In that three years, you would&#x27;ve had a great head-start on both professional experience and financial health.<p>Food for thought. Your statement just assumes the startup will do well and that&#x27;s not a guarantee. There isn&#x27;t a guarantee a company you work for will be around forever either, but the likelihood is far greater.
