Perhaps. To be quixotic (quijotesco) means to be unrealistic or impractical.
Someone could say that you are a wishful thinker.
Here are some examples:
- Mr. Sánchez`s political aspirations are quixotic at best (…aspiraciones son quijotescas en el mejor de los casos).
- How quixotic of you! ¡Qué quijotesco de tu parte!
- Mr. Biden, the President of the United States, has a quixotic attitude to life.
The adverb is “quixotically” (de manera quijotesca o como un quijote). An example:
- Mr. Putin is behaving quixotically.
So have you sometimes been quixotic and behaved quixotically?
