What are the ways to improve your WordPress site’s speed?

Could you recommend me the ways to improve my WordPress site’s speed?
One of my colleagues suggested me these tips:
- Optimize images for speed on FLATsite (https://flatsite.com/)
- Use faster plugins
- Choose a theme that’s optimized for speed
So, i need to consult with you on what way is right for me and why.
Any inputs?

To me, the WordPress experience with FLATsite.com is more personal and that extra level of service is easily worth the few extra bucks. Good job! Impressed with the speed improvement.
