As I've mentioned a lot, I believe it's important to be less excited about the Dunya and more about Islam, there are a number of ways you can do this.
Firstly by getting excited about things in Islam. Like Friday's- (yes it's the end of the week) but it's also Jummah and a day where we should try to make lots of dua to Allah particularly between asr and Maghreb. Also a good day to groom ourselves and givecharity -a day solely for contemplation.
Also how about optional fasting I think this helps you to be more grateful about small things because you are grateful for food and you are more conscious of Allah.
Attending talks aswell as reading Islamic books that are thought provoking, keeping yourself busy with exercise as well as maybe brushing up on tajweed.
The sole aim is to make yourself happier with simple things. Simple things from Islam, that way you are more appreciative.
I am aware it is more easier to talk about when you have free time on your hands. But if you don't have as much time as me( if you're a college uni or full time worker) you could just try optional fasting because that doesn't require time. And I'd say if you can, attend Jummah but if you can't you can still do the sunnahs of Friday.
You also can read thought provoking books to and from journeys as for excercise I think it's important for your mental wellbeing so even once a week or 20minutes a day in the morning or something would definitely help.
Also prayer- when we pray we should make an effort to look nice. As in adorn a nice abaya maybe put some attor on (not on a abaya you wear out) use miswak make sure you're prayer mat is on something soft like a blanket unless you have a carpet so you're not touching down on hard ground. Maybe light a nice smelling candle- make your room nice and warm... That's what I do anyway and it puts me in a good mood to pray and I feel much more concentrated and excited to pray.
I remember when I was in college I had this problem with praying. I was so focused on my work I couldn't completely give my attention to prayer but it is really important to forget worldly matters when praying so you can really connect with Allah. Otherwise it's pointless. Just think about it like this whatever revision or homework that needs doing will still be there after prayer you thinking about it is simply aiding Shaytan in his motive to distract you- and in order to really be successful in your affairs, you must trust in God and pray to Him instead of worrying or dwelling.
Well that's all....
