Hello World & Hello Me

Who I am & why I’m doing this

My name is Mildrette. I’m a junior Android developer at Afkanerd in Bamenda, Cameroon. I started this challenge today because I’m tired of letting procrastination win.

I live with PCOS/PMDD and some days the fatigue and brain fog make it feel impossible to show up. But I’m done waiting for a perfect day. Today is day one.

What I learned today

Today I learned about variables in Kotlin. There are two types:

• val — a value that cannot change
• var — a variable that can change

// val cannot be reassigned
val name = "Mildrette"

// var can be reassigned
var day = 1
day = 2 // this works fine

Kotlin can also infer the type — you don’t always have to tell it what type a variable is:

val city = "Bamenda"     // String
val year = 2025          // Int
val isStarted = true     // Boolean

Code I wrote today

fun main() {
    val name = "Mildrette"
    var day = 1
    val challenge = "30-Day Learning Challenge"

    println("Hello! My name is $name")
    println("Today is Day $day of my $challenge")
    println("Let's go!")
}

Output:

Hello! My name is Mildrette
Today is Day 1 of my 30-Day Learning Challenge
Let's go!

How I felt today

Today felt exciting and scary at the same time. The procrastination voice was there — telling me to start tomorrow. But I didn’t listen.

I kept it simple today. Short, clean, working code. That’s enough for day one.
