That depends on the kind of project you are working on, If you are highly motivated and the project is fun you may work for longer hours, my case I could go as long as 8hrs non-stop but if it&#x27;s not as described above then 3hrs max.<p>Two years ago I experienced a burnout for the first time, for a 23-year old freelancer, I knew nothing about burnouts and thought I was severely depressed. My motivation level was 0.<p>So if your job is fun then you may find 8hrs a day not even enough, but it&#x27;s not your fault, it&#x27;s your employers.
