[Question] Is laziness immoral?

So I have just read Peter Singer’s book “the life you can save”, and I can’t stop thinking about effective altruism as a moral obligation in everything that I do. Singer’s drowning child analogy refers to money, but also time, as things that must be sacrificed in order to be moral. Greed and Gluttony I can manage, but Sloth? The pressure in knowing that I can’t sit around and do f**k all—that I am a bad person for doing so—leads me to doing it more!

Some insight: I am 17, live in the UK, am anxious and struggling to get a part-time job due to the pandemic and college work, and my household’s annual income is <£30,000. After reading TLYCS, I feel that I ought to get a job, otherwise I am wasting the privilege that I have, that puts me above those in developing countries who, at my age , have to work to earn pitiful amounts of money to survive: It would be wrong for me not to get a job so that I can donate.

How should I approach this effectively?
