1. Second conditional: "I probably wouldn't continue if I knew for sure it was a waste of time" uses the second conditional structure (would + base verb, if + past simple), which is great for expressing hypothetical situations.
2. Present simple and present continuous: "I try to be quite mindful..." and "there are so many things I want to do" use present simple to talk about habits and general truths.
3. Infinitive of purpose: "to be quite mindful", "to do", "to lose all motivation", and "to move on" all use the infinitive form to express purpose or intention.
4. Parallel structure: "learning something new or just relaxing properly" and "something more meaningful or enjoyable" both use parallel structure, which makes the answer sound smooth and natural.
