Questions & Answers about Cuando no sigo mi propio enfoque, me siento decepcionado y un poco harto de mí mismo.

Why is it cuando no sigo and not cuando no siga? I thought cuando often used the subjunctive.

Both are possible, but they mean different things.

• Cuando no sigo mi propio enfoque… (indicative, sigo)
  This talks about a general, habitual situation – something that happens whenever this condition is met.
  → When(ever) I don’t follow my own approach, I feel…

• Cuando no siga mi propio enfoque… (subjunctive, siga)
  This usually refers to a future or hypothetical time that hasn’t happened yet.
  → When I don’t follow my own approach (in the future / in that case)…

In your sentence, the speaker is describing a pattern or general truth about themselves, so the present indicative sigo is the natural choice.

What verb is sigo from and why is it spelled that way?

Sigo is the first‑person singular (yo) of seguir in the present tense.

• Infinitive: seguir – to follow / to continue
• Conjugation (present):
  • yo sigo
  • tú sigues
  • él/ella/usted sigue
  • nosotros seguimos
  • ustedes/ellos/ellas siguen

The gu → g change (seguir → sigo) keeps the hard g sound before o. This is a regular spelling change in Spanish (compare tener → tengo, venir → vengo).

Why is it me siento and not estoy? Both translate as “I feel” sometimes.
