Sometimes I feel, for example, when I spend long hours in steemit, that I am wasting my time. Obviously, if I only use that time to read, without commenting or voting, and even to prepare myself to see how things work around here, I will obviously be wasting my time. I think you have to have a balance: there are hours you can devote to leisure and socialization, but there are times when the work has to be more continuous and hard. At steemit there are times when publishing so much is not profitable, then you take the time to do and review other things. Greetings
It is only a waste of time if thinking too short-term I think as the current pay off for most is not much now but, in a year or two the work put in now will be worth a lot more (hopefully)
