Things I looked for when choosing my company: 

1) High P/FCF

2) Positive sales growth over the past 5 years

3) Positive ROI

For my investing purposes, I am mostly concerned with the company's current state and future potential. Being a young investor, I am less concerned with making money quickly. Therefore, I wanted to choose a company with high P/FCF, positive growth and ROI. I also wanted to choose a company that I like, and that I purchase goods/services from on a regular basis. Costco is the perfect fit for these qualifications.
