I'm looking to get the phrase "life is what you make it" translated to
latin for a tattoo and I'm having a very hard time with it. Is there
anyone here who can help me?

Hi dietzsm-ga -

I suggest you might want to pick the most idiomatic Latin expression
that also expresses your sentiment.  As you know, the way we put
things today may be a lot different than the way a Roman would have
put it.

So--one suggestion is to be as idiomatic as possible and use an
expression that was common in ancient times:

1. Nil difficile volenti 
	Literally:  Nothing (is) impossible to the one who wants it.

Another suggestion is to apply the above to "life" by saying:

2. Vitam agas tanquam nil difficile volenti
        Literally:  Live as if nothing (is) impossible to the one who wants it.

Another more literal but accurate expressions is:

3.  Vitam agas vitam tuam
        Literally:  Make the life you live YOUR life.  [very roughly:
you make it; you live it]

The last one is the closest the Latin can come to your exact words,
but I myself would go with the first, "nil difficile volenti," which
captures the sentiment most classically.

I  used Cassell's dictionary for this translation.

You can take a look at many Latin phrases that are used used in
English at this website:

I'm sure your tattoo will look super.

A direct translation  word for word is 

"vita est quis vos planto is"

gramatically i am unsure if this flows..

No, it doesn't, and my suggesting is probably also incorrect  ( I am
very unsure about the verb form):

vita qua facies

"Vita qua se facies est." This is a strict and literal translation.
The problem, though, is that "life is what you make it" is idiomatic.

If you want "You make your own life"--as in "one makes one's own
life"--"Quidam sua vita faciet." Or literally "you (proun.) make your
own life"--"Tua vita facies."
