Most people find it difficult to pray. You'd think it would be easy but interestingly, it's not. In this age of instant stimulation, social networking and immediate feedback, the habit of praying just doesn't do it for many.
Most Christians know that it's a spiritual discipline and something one should naturally do, but invested input doesn't always equal expected output. Nor does answered prayer come in the Pentium or Thunderbold speed we're used to in the 21st century. Therefore, prayer is oftentimes viewed more as a burden than a privilege. A chore versus a blessing.
If you're one of the many who honestly feel this way, realize you're being conditioned by another spirit (Ephesians 2:2). Prayer is just talking to God. Like with every relationship, the more you know and understand God, the easier it becomes to engage with Him.
Most Chinese believers share with us that they were never taught how to have an intimate relationship with their physical father, so initially, it is difficult to know what to say to their heavenly Father. That's totally understandable.
