Correção de Texto: If I could do it again

If I could do it again

When I was a teenager I attended an eletroelectronic course. In one of the pratical lessons we had to fix a electric motor. The teacher advises us that it is very recommended to perform some tests before to turn on the motor, but I ignored them. If I could do it again I would pay more attention on the teacher. My motor almost get burnt and had to spend a week fixing the damage.
