In athletics there are two types of what we will call movement capacities; static & dynamic. Think of flexibility as sit & reach, static movement capacities. Now mobility is having proper overhead squat efficiency, dynamic movement capacities. If you are immobile it may not be just stiff muscles. The body can suffer from restricted fascia (a complex autonomous tissue that actually encapsulates every component in the body, from muscles and bones to organs), weak and immobile joint capsules, the brain can control and hinder immobility, even tattoos can impede your range. Tattoos staple the topical fascia to the skin & create lasting scar tissue. Nothing personal against artwork. A recent article in BroScience Weekly says that if you were drunk or have no idea what the Chinese symbol on your delt stands for then it doesn't count, lol. The point is that you need both static and dynamic flexibility, if you do it properly at night it can even decrease belly fat!
Last point is that flexibiliy/mobility are interesting in that as you age you lose the abilities to maintain the qualities. Daily maintenance is required to keep mobile. Think about it, a pack of lions usually hunt down the old weak and stiff wildabeast in the herd. Don't be that guy ;)
Here is a great video on training mobility.

WRITE THIS DOWN: Train Mobility, just as diligent as you would train your favorite body part. Time will only hurt your opportunity at improving flexibility, for both dynamic and static mobility. A good time to start working on mobility of all kinds is yesterday. Having too good of mobility is like too good of credit score, doesn't exist.
Tomorrow we jump into work capacity and endurance, tasty. Ciao
