How to unlock the Don't Run, You'll Just Die Tired achievement in The Bureau: XCOM Declassified - Definitive Guide
Once you have the sticky grenades unlocked and your back at the base head to the firing range. Hit the button and someone will throw an alien out onto the firing range. Simply lift the alien with your ability then aim and stick a grenade on them when they are in the air. Once the grenade explodes step back out of the shooting cubicle and your grenades and ability will recharge instantly. Rinse and repeat.
+1 Thumbs up...
Use the dazing ability of your teammate which makes the enemy standing in one place for a few second. Then just walk close, aim with the grenade and stick it on. Repeat 10 times and the achievement will pop.
The easiest way in my opinion is to use Lift on an enemy and then pop the grenade on him. Works like a charm.
Make sure to stick Outsiders only (the humanoid aliens) since all others don't count for this. You can stick all sorts of Outsiders though. Commanders, Phantoms, standard ones...doesn't matter as long as it is an Outsider.

Sticky Grenades are obtained later in the game. Outside enemies are classified as any of the "Humanoid" looking aliens such as the Outsiders, Phantoms, or elite versions. The easiest way to make sure they stick to the target is to get close to a singled out enemy, and aim the impact circle directly onto the target. Make sure you have your agents do something else so they don't kill your target.
Tip (Credit to Drexiel)
This will count on any Outsider, Phantom, Scouts or Commanders, and it should unlock upon your 10th sticked 'nade. Use LIFT and then throw a grenade on the lifted enemy. Trying to stick a 'nade into a hiding enemy can be hit or miss, literally. So if you did like me, and picked the Heal upgrade instead of the grenade upgrade, and you have 3 grenades instead of 6; use the method I mentioned.
Sticky grenades are first encountered in mission four. The Achievement description is a bit misleading, it actually doesn't require Outsider type enemies, any alien will work. Mutons and Sectopods are the best enemy for this. First immobilize them with lift, and then stick them with three or more grenades and watch the fireworks.
