How would you force Stata to use observations with missing values in any regression? What's a "best case scenario" here? Have you thought about multiple imputation?

I have around 170 firms and around 16 variables in a panel data with firms having data for at the most 5 years. However,  I dont have data for all the firms for all the variables. So, when I run regression command, stata only picks the data which has the data for all the variables and my results are inappropriate.

However, when I run the regression with each independent variable separately, I get the desired results. Is it valid to run separate regressions for all the variables and analyse the results. Or, is there any way where I can force stata to consider records which do not have all the data and take a best case scenario? 

Any help is appreciated. 

Thanks!
Deepti
