Help translating these intellectual quotes?

Question

I am trying to find proper translations for the following seven quotes. I have found translations of some of the quotes online and through the translator that sound right, but I am not sure if they are correct. Any help proofreading and filling in the remaining quotes is greatly appreciated.

(1) The secret of change is to focus all of your energy, not on fighting the old but on building the new. El secreto del cambio es enfocar toda tu energía, no en luchar contra lo viejo, sino en construir lo nuevo.

(2) To find yourself, think for yourself. ??

(3) To be is to do. Ser es hacer.

(4) He who is not contented with what he has, would not be contented with what he would like to have. ??

(5) Strong minds discuss ideas; average minds discuss events; weak minds discuss people. Las grandes mentes discuten ideas; las mentes promedio discuten acontecimientos; las mentes pequeñas discuten a la gente.

(6) The only true wisdom is knowing that you know nothing. La única verdadera sabiduría está en saber que no sabes nada.

(7) I cannot teach anybody anything; I can only make them think. Yo no puedo enseñar nada a nadie; sólo puedo hacerlos pensar.

5. Discutir means to quarrel, not to discuss. - annierats, Oct 6, 2015

Answer 1

¡Hola!

(2) Para encontrarte a ti mismo, piensa por ti mismo.

Answer 2

I'll try #2:

Answer 3

I'll have a crack at : 4) He who is not contented with what he has, would not be contented with what he would like to have. ?

Quién no está contento con lo que tiene , no sería contento ni siquiera si tuviera todo lo que le gustaría tener. ??

or lo que tenga/ no sería??? Difficult one! - annierats, Oct 6, 2015

You have "estar" in the first claudr and "ser" in the sceond. ¿Por qué? - Daniela2041, Oct 7, 2015

first "clause" (bad typo---just can't control these fingers.!) - Daniela2041, Oct 7, 2015

Answer 4

(3) To be is to do

This is nearly impossible!

¿Vivir haciéndolo?

It's only a suggestion.

Mejor sería "Ser es hacer." - Daniela2041, Oct 7, 2015

Yes, but I would never understand that if anybody said it to me..Actually, I have to think to understand the Englsish version..Probably I'm born lazy.. - annierats, Oct 7, 2015

Thanks for your responses! Haha, I know what you mean. The more I think about it, the more I don't understand. - Mattsa, Oct 9, 2015
