Learning Two Languages at The Same Time

I love the Spanish language, I find it very sweet and I am very interested in learning it, but the problem  matter is that my English is not good and I am trying to improve it. There is a French proverb that says:« On ne peut pas courir deux lièvres à la fois » or 'We can't run after two rabbits at the same time'. I am still thinking about hesitating between improving my English and then moving to Spanish or to start learning Spanish while improving my English!!!!!!!
